Toast Notifications on Dev Alpha C (10.1)

My toast notifications on the Dev Alpha C do not display properly. The message that I have runs 2 lines (also contains a button). The text does not appear to adjust properly. If there is only 1 line, the toast notification appears correctly, but when there are 2 lines the second line runs along the bottom border of the toast. The toast notification is working without issue on my Z10. Not sure if it is a Dev Alpha C issue or 10.1?
